OSGILLA'I'ING MECHANISM FOR WASHING MACHINES.

Application filed December 17, 1923. Serial No. 681,277.

To all whom it may concem:

Be it known thatI, EDWARD F. VANnpI-r- BOSCH, a citizen of the UnitedStates, residing at Laporte, in the county of La Porte and State ofIndiana, have invented certain new and useful Improvements inOscillating Mechanism for Washing Machines, of which the following is aspecification.

The invention relates to oscillating mech anism for washing machines,and has for its object to provide a device of this character' wherein apivoted washing machine receptacle will be operated in a manner wherebyjerking or hammering of the parts at the time of reversal of movement ofthe receptacle will be obviated.

A further object is to provide oscillating mechanism for washing machinereceptacles, which mechanism comprises a slidable crosshead mounted inguides of one end of the receptacle, and provided with an internal geardriven by drive pinions at a fixed point for reciprocating the crosshead in the guides and imparting an oscillatory movement to thereceptacle. Also to provide an idle gear carried by the cross head andwith which idle gear the drive pinion meshes" for holding the drivepinion in mesh with the internal gear during the reciprocation of thecross head by the drive pinion. The

idle gear also acts as a thrust bearing for the drive pinion.

A further object is to slidably mount the cross head radially to theaxis of the receptacle, thereby insuring oscillations of equal length toeither side of the axis of the receptacle.

A further object is to provide a motor for driving the drive pinionthrough the medium of a worm and worm gear carried by the frame of thewashing machine adjacent the crosshead, thereby providing a compactstructure.

A further object is to provide an oscillating mechanism for a washingmachine receptacle wherein the pivoted receptacle is oscillated throughthe reci rocation of a radially movable crosshea mounted in guides. I

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a perspective view of a washing machine,showing the device applied thereto.

Figure 2 is a front elevation of one end of the washing machinereceptacle, showing the oscillating mechanism applied thereto.

Figure 3 is an enlarged side elevation of one end of the washing machinereceptacle. showing the oscillating mechanism applied thereto.

Figure 4 is a horizontal sectional view through one end of thereceptacle, taken on line 44 of Figure 3.

Referring to the drawing, the numeral 1 designates the frame of thewashing machine and 2 the receptacle thereof, in which receptacle,articles of clothing are placed during a washing operation. In washingmachines of the oscillating type, as at present constructed, when thedirection of oscillation is reversed, a jerking or hammerin of the partstakes place incident to the sudden reversal. To obviate this difficult;the receptacle 2 is oscillated on its pintles 3 by means of a crosshead4, which crosshead is slidably mounted in crosshead guides 5 disposedwithin a casing 6 secured by means of rivets 7 to one end of thereceptacle 2. The crosshead 4 is'radially movable in relation to thepintles 3 of the receptacle, thereby insuring the same length ofoscillatory strokes to each side of the vertical longitudinal center ofthe receptacle 2, consequently a uniform agitation will take'placewithin the receptacle 2 during the operation of the device. Grosshead 4is provided with an internal gear 8, with which gear a fixed drivepinion 9 meshes, which pinion is carried by a horizontally, disposedshaft. 10, which is rotatably mounted in a bearing 11 of the outwardlyextending portion 12 of a gear casing 13. Disposed on the upper end ofthe gear casing 13 is a conventional form of motor 14, preferably anelectric motor, which motor has its drive shaft 15 vertically disposedand provided with a worm 16, which meshes with a worm gear 17, thereforeit will be seen that the drive pinion 9 is driven by the motor 14, andsaid drive pinion will be constantly rotated in one direction by themotor during the operation of the motor, but will remain at a fixedpoint, as the same is supported by the portion 12oftheicasing 13 of theframe 1. During the rotation of the drive pinion 9, the crosshead 4 ismoved towards I ,the axis of the receptacle 2, and at the same internalgear as the drivepinion 9 moves time gradually moved to one side ofthelongitudlnal vertical center of the receptacle, thereby swinging thereceptacle on its pintles 3 to the dotted line .position shown in Figure3, at which time the .drive pinion 9 assumes a dead center positiongradually, consequently jerking or hammering of the parts is obviated,as there is'momentarily no sliding movement of the crosshead 4 when itassumes the dead center position as shown in dotted lines in Figure 3.However as the pinion 9 continues to rotate and which spider is providedwith a stub shaft,

18, axially disposed in relation to the internal gear 8, and on whichstub shaft is rotatably'mounted an idle gear 19. v The idle gear 19moves with the crosshead 4, and meshes with the drive pinion 9,consequently not only ,acts as a thrust bearing for the rive inion 9,but at the same. time maintains t e drive pinion 9 in mesh with thearound the internal gear 8, thereby insuring a positive operation of thedevice and the reciprocation and oscillation of the crossheagl9 4 duringthe rotation of the drive pinion From the above it will be seen thatadriving mechanism is provided for oscillating washing machinereceptacles wherein the structure is compact, and the receptacleoscillated by the reciprocation of a crosshead in guides, whichcrosshead is simultaneously oscillated. It will also be seen that thecrosshead is driven by a drive pinion dis-- posed at a fixed point, andmeshing with an internal gear carried by the crosshead, thereby gettinga maximum oscillation in a minimum amount of movement of the crosshead.

The pintle 13 of the receptacle 2, which is 4 disposed adjacent thedriving mechanism may be mounted in any manner desired,

however it is preferably carried by a bar 20,

which connects the outer sides of the guides 1 5, thereby allowing thecrosshead 4 to move between the pintle 3 and the adjacent end of therece tacle2 behind the bar 20, therefore 1t will e seen that thecrossheadwill. not

come into engagement with the pintle 3 in its upward movement, and thedriving mechanism may be placed relatively close to the axis of thereceptacle 2. 4
